HAZOP Preparation Safety Requirements

The Dome Safety & Risk Consultancy team is highly experienced in HAZOP preparation safety requirements and has undertaken a large number of studies for the oil & gas industry as well as other industries in the region.

There are various Hazard Effects Management Process studies which are carried in process industries such as HAZID, HAZOP, HAZAN, etc. HAZOP (Hazard Operability Studies) is used as a part of process hazard analysis and is a very important tool for the design verification. The technique was originally adapted into general use in 1977 by Chemical Industries Associations and later implemented by many industries. It is now used worldwide in line with IEC 61882 Guideline for Hazard Operability Studies.

The HAZOP study systematically and rigorously examines the plant process operation to identify credible deviation from the design intention in the context of the complete system that can contribute to potential Safety, Health and Environmental hazards and operating problems.

The HAZOP is carried out under the guidance of a trained and experienced study leader or chairman who ensures comprehensive coverage of the system under study using logical analytical thinking. The HAZOP team consists of the study leader, normally assisted by a Scribe, and various subject matter experts who identify the process design deviations operational disturbance and operability issues using sets of guide words. All such deviations are recorded for further evaluation and resolution with the help of the scribe. The role of the third-party HAZOP chairman is crucial to the success of the HAZOP and Dome’s well qualified senior consultants ensure that the team is fully prepared for the task.

The HAZOP study method is applicable to all types of process industries and can be applied in any type of process system such as continuous, or batch process. HAZOP technique is used in the life-cycles of facilities or at every phase of projects such as:

  • Conceptual / Pre-FEED
  • FEED (Front End Engineering Design)
  • Detailed Engineering
  • Revamping / Modification
  • Start-up / Commissioning and Decommission
